Watch live: SpaceX Falcon 9 rocket launches 21 Starlink satellites from Vandenberg, California

Watch live coverage as SpaceX launches a Falcon 9 rocket with 21 second-generation Starlink internet satellites. Liftoff from pad 4E at Vandenberg Space Force Base is scheduled for Sunday, July 28, at 2:22 a.m. PDT (5:22 p.m. EDT, 0922 UTC). The first-stage booster, B1071, making its 17th flight, will land on the drone ship 'Of Course I Still Love You' a little more than eight minutes into the flight.

The Starlink 9-4 mission includes 13 satellites capable of providing direct to cellphone services.

Our live coverage with commentary from Will Robinson-Smith will begin about 30 minutes before launch.

3 launches in 48 hours! 🎉
That’s quite the return to flight only SpaceX could pull off…

Stage 1 landing just blows my mind every time. The whole project is just incredible.

IT NEVER GETS OLD. Falcon 9 is a thing of beauty

Space X has an anolamy and in two weeks has a resolution and is flying again successfully. If it was Boeing it would be two years! Starliner stuck at ISS. Hopefully astronauts will find another way home.

Amazing work done by the great space x team 🎉. Congratulations

Edit: the landing is perfect ❤

Lets go spaceflight now! I have been watching the views go from a few hundred to now 1.3k in 3 hours. gooood

How do Falcon 9 rockets get to Vanderberg?

[DadNotmyname]

I would design these rockets with a telescopic structure, featuring inner and outer tubes in nested cylindrical sleeves, allowing them to expand and contract in length. Similar to an expanding aerial, this design would let the rocket function like a caravan that grows in size upon reaching its destination. In compact form, the rocket is solid and aerodynamic, suitable for launch and flight. If the nose cone were made slightly larger in diameter than the rocket, it could slide down onto the rocket and clamp in place. In space, this nose cone could slide up, extending the length of the rocket and exposing more of the rocket cylinder. The now exposed part could have any shaped door that was not previously exposed to space. This transformation allows the rocket to shift from a transportation vehicle to its intended functional design, with modular compatibility enabling attachment and detachment of different modules, enhancing its versatility and functionality. When the mission requires, the sleeves can retract, restoring the rocket to its compact form for further travel or re-entry, ensuring both versatility and safety throughout the mission. Additionally, in the presence of debris or meteors, the delicate entrances to the interior are shielded by the more robust outer shell.

As for the flaps, they should be eliminated to simplify the design. The nose cone should not simply be round but should start with a tip, then form into an oval shape, and then back to fit the round shape of the rocket. This means the nose cone will act like a wing. By spinning the cone on its axis, it can divert the flow of the atmosphere to control the flight path.

Thanks FAA, now it's out in the open your disdain for Elon Musk/SpaceX/Tesla A launch at 2am? What a joke

Is racism in space? Prayers for the Massey Family
